Senior Backend Engineer · Go · 20 years in software
I build and lead backend systems at scale. Today I write Go services at Zerion that index blockchains and serve portfolio data to major wallets and exchanges. Before that, I've designed protocols handling 200k+ messages/second at Apple, led platform teams, and coordinated cross-team projects across 8+ engineering teams. I work in Go, Python, Java, TypeScript, and whatever gets the job done.
